The company that was to become Panasonic was started on March 7, 1918, when Konosuke Matsushita moved from his tiny dwelling to a larger two-story house and set up Matsushita Electric Housewares Manufacturing Works.
In the 1920s Matsushita began regularly launching products. In 1927, he produced a line of bicycle lamps that were the first to be marketed with the National brand name. During World War II the company operated factories in Japan and other parts of Asia which produced electrical components and appliances such as light fixtures, motors, electric irons, wireless equipment and its first vacuum tubes.
In 1961, Matsushita traveled to the United States and met American dealers. The company began producing television sets for the U.S. market under the Panasonic brand name, and expanded the use of the brand to Europe in 1979. Throughout the 1970s and early 1980s, Matsushita continued to produce high-quality specialized electronics for niche markets, such as shortwave radios, and developed its successful line of stereo receivers, CD players and other components.
Fast-forward to the digital era, which has pushed Panasonic to pivot further, including ceasing production of analog TVs back in 2006. In 2008, the company finally changed its name from Matsushita Electric Industrial Co., Ltd. to Panasonic Corporation - Panasonic had been one of its many brands.
By 2013, Panasonic divided itself into four companies based on its four primary business divisions: appliances, eco-solutions, AVC networks and automotive and industrial systems.
Today, the company has become a major Japanese multinational electronics company, headquartered in Kadoma, Osaka. As of March 31, 2012, Panasonic employed about 330,000 staff and had around 580 subsidiary companies.
